In the evolving landscape of automotive and industrial manufacturing, engineers face a recurring dilemma: standard elastomers like NBR (Nitrile) often fail under modern high-temperature conditions, while high-performance Fluoroelastomers (FKM) can drive project costs beyond budget.
Enter Acrylic Elastomer (ACM).
Often undervalued, ACM rubber represents the ideal technical bridge. For applications demanding superior resistance to hot oils and oxidation without the premium price tag of FKM, FluorinChem’s Acrylic Elastomer CGPA600 provides the perfect balance of performance and cost-efficiency.
What is ACM Rubber (Acrylic Elastomer)?
ACM (Alkyl Acrylate Copolymer) is a specialty rubber designed specifically to withstand harsh environments where heat and oil intersect. It is composed of a saturated backbone, which grants it exceptional resistance to ozone, oxidation, and weathering—properties where unsaturated rubbers like NBR often fall short.
Our flagship grade, CGPA600, is engineered to deliver consistent processing characteristics and reliable end-use performance, making it a staple material for the automotive industry.
Why Choose ACM Over NBR? The Technical Edge
While Nitrile rubber (NBR) is the industry standard for general oil resistance, it has a significant limitation: Heat.
As engine compartments become more compact and turbocharging becomes standard, operating temperatures rise.
·NBR Limitation: Typically degrades rapidly above 100°C - 120°C, leading to hardening and seal failure.
·ACM Advantage: FluorinChem’s ACM remains flexible and effective at continuous temperatures of 150°C and intermittent peaks up to 175°C.
Furthermore, ACM offers superior resistance to transmission fluids (ATF) and sulfur-bearing additives found in modern gear oils, which can attack other elastomers.
Key Applications: Where CGPA600 Excel
The unique properties of our Acrylic Elastomer CGPA600 make it the material of choice for critical "under-the-hood" components:
1. Automotive Transmission Seals
Automatic transmission fluids are chemically aggressive and hot. CGPA600 provides the necessary chemical resistance to prevent leakage over the vehicle's lifespan.
2. Turbocharger Hoses and Air Ducts
With excellent resistance to heat aging and good damping properties, ACM is widely used for hoses that must withstand engine vibration and high thermal loads.
3. Valve Cover Gaskets and Oil Pan Seals
For static sealing against engine oil, ACM offers a significant upgrade over NBR, ensuring long-term reliability without the high cost of FKM.
Processing Benefits of FluorinChem CGPA600
For molders and manufacturers, raw material "processability" is just as important as end performance. We have optimized CGPA600 to address common manufacturing challenges:
·Fast Curing Rate: Improves production cycle times.
·Good Mold Release: Reduces scrap rates and cleaning downtime.
·Consistent Viscosity: Ensures batch-to-batch stability for injection and compression molding.
Conclusion: Optimizing Your Material Selection
In the race for higher efficiency and durability, selecting the right material is critical. If your application involves hot oil, transmission fluids, or temperatures exceeding the limits of NBR, ACM Rubber is your strategic answer.
FluorinChem is committed to supplying high-grade Acrylic Elastomers that help you maintain a competitive edge.
